IMPROVEMENT IN DRAFT-EQUALIZERS.

Specification forming part of Letters Patent No. 160,355, dated March 2,1875; application filed January 25, 1875.

To all whom it may concern Be it known that I, LIBERTY J. SEELY, ofWaldron, Shelby county, Indiana, have invented a new and ImprovedDraft-Equalizer, of which the following is a specification:

Figure 1 represents a top View of my improved draft-equalizer for plowsand other implements. Fig. 2 is a side view. Fig. 3 is a bottom view ofthe same; Fig. 4, a detail transverse section of the same on the line ac, Fig. 3, showing braced cross-bar, and Fig. 5 is an end view of theplow-beam with front View of clevis.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide a simple and efi'ectivedraft-equalizer for three horses, to be attached to plows and other agricultural implements, by which the land-side is relieved of twisting anddrawn in a straightforward direction, gaging at the same time the depthand width of furrow to the draft. The invention consists of a slottedclevis, secured by supporting braces and bars at the front end of theplow-beam, at suitable distance toward the land-side of the same. Theclevis carries in a sliding and adjustable drafteye a draft-rod with theusual three-horse doubletree, being strengthened by draft and stay rodsattached to a lateral crossbar and the rear and front part of theplow-beam.

A represents the plow-beam, to the front end of which is firmly andsecurely bolted the slotted clevisplate B, being set, by means ofsupporting-bars a and top braces b, the required distance from the beamtoward the land-side. The adjustable draft-eye 0 slides in the slottedclevis, and is clamped to any position thereon by the draft-nuts d,according to the depth and width of furrow required. The draft-rod 6passes through the draft-eye O, and is adjusted therein, carrying at itsfront end the customary three-horse double-tree, being connected at itsrear end by clevis and bolt to a rigid cross-bar, D, that is firmlybolted to the side of the plow-beam and stiffened by braces f. Anadditional stiffening-bar, g, runs from the clevis-supporting frame,along the under side of the plow-beam, to the cross-bar andplow-standard. A rear draft-rod, e, connects the end of the cross-barwith the rear end of the plow-beam at the handles, while a stayrod, h,is clevised to the opposite end of the crossbar at the same distancefrom the plowbeam as the draft-rods, and bolted rigidly to the front endof the plow-beam.

The draft of the three horses pulling abreast is equalized in such amanner that the twist ing and irregular running of the plow is avoidedand a straight and steady running of the same is provided, while at thesame time the width of the furrow is exactly gaged and regulated.

The construction is simple, yet strong, and prevents, by theequalization of the draft on the plow-beam, the breaking or other injuryof the plowshare, while giving greater satisfaction than the morecomplicated equalizingattachments.

Having thus described my invcntion, Iclaim as new and desire to secureby Letters Patent The improved draft-equalizer for plows, &c.,composedof a slotted and rigidly supported and braced clevis, B, at thefront end and land-side of the plow-beam, with adjustable draft-eye O,in combination with the strengthening draft and stay rods 0 e h,clevised to laterally-braced cross-bar D and bolted to front and rearends of beam, substantially as specified.

LIBERTY J. SEELY.
